This invention relates to improvements in l'antenn'asupports and more particularly to l one which is collapsible and whichis hollow.

Anobject' ofjthe invention'is to provide a hollow antenna; support for coil antenna, f

which is collapsible *and is: provid'ed*w-ith suitable means to permit the fillingor inflationof the same, inorder that it maybe held in extended position for supporting coil 3 antenna.

' with a valve or the like 'to permit the filling of the same, with eitherair, water, or fine powdered or granular material, in orderto Y retain thesame in extended form, and also to provide for'the filling of the support with material of a; particularly heavy nature at r the bottom portion, so that it will be retained in upright position, by this. substantially hea weight at the bottom.

"Other objects of the .'nvent1on will be more clearly pointed'out in thefollowing detailed description and in the claims directed to preferred embodiments of the invention, it being understood, however, that many vari-- ations' may be made of the size, shape, and arrangement of parts, of the. support, for antennae of difierent characters, without des parting from the spirit and scope of the invention, as set forth.

V In the drawing, forming a part of this provided.

application Figure 1 1s an elevational view of an "an- I tenna support and the antenna mounted .thereon,a portion of the basebeing shown in section.

Figure 2 is a view of. an antenna-support of slightly diiferent form. j 1

Figure 3 is a view of another form of hollow coil support, wherein the same is formed of an annular tubular member and a ,coil

mounted within the support, when extended.

Figure 4 isadetail perspective view of another form of coilsupport, which may be In Figure 1,the support is indicated at 1,

V i which is formed of'a substantially cruciform member provided at 2 with suitable means for mounting the convolutions of the coils 3, forming the antenna, the terminals of c which are indicated at 4, so that the antenna 1 may be suitably connected with a radio.

receiving set. -The cruciform member 1 is suitably carried by a base portion 5, which is formed at the end of one of the arms of V the invention 5 is to. pro- I vide a hollow collapsible antenna support,

7 the cruciform member, as illustrated ih'Figure and which provides a substantially largefflatfbase, for supporting'the antenna I on thesurfaceof a table, floor, orfthe'ilike.

1 The entire 'cruciformmember and .the base I 5 a're'fformed of a suitable flexible material, rsuch'as' rubber, canvas, or otherform'. of fabric'orthelike, solthat'the same is hollow of opening, in order to provide for access .to

the interior of the support, so 'that'it may be filled with air, 'sand,powder, water,"or any other filler materiah-which will hold the same "in extended position,"as' indicated,

theopening being closed, after the same 1s .filled, *in order to] prevent the escape of the contents of the member. In order times, in an upright position, as shown in Figure 1, it is preferably that some heavy that thecoil support. will be retained, at all I material, indicated diagrammatically at 7, be placed in the s'upport,'so that it1wi1l be? positioned in the base portion 5, in order to provide ,a greater weight in this base portion, for retaining the cruciform member in upright -pos1tion., Sand could be used for this purpose, when-the support is inflated with air, and it will be appreciated would I 'eificiently hold; the cruciform member in;

upright position. In- Figure 2, the support is illustrated at 8,]as being formed of a-tu- -bular member arranged in substantiallyf square form, and adapted to support the coil 9 within the same,' by'suitable hanger-means 10. I Thevalve' or opening is indicatedyat 11, by'means of which the support may be filled or inflated, for retaining it in ex-' tendedposition, so as to support the coil 9.

A similar structure isishown in Figure :3,

'whereina support 12'is formedof a tubular member-of even section throughout, and

arranged, when inflated to assume a ring like form, for supporting the coils 13 there-' in, the valve'or opening being in dicated at 14, and a suitablehe'avy material at 15, for

retaining; the support in a predetermined v position at all times;

ing the valved opening at 17 ,in order that the same may be filled. This cubic member In Figure 4 the hollow coil support is in- "dic-atedat 16, which is-of a cubic form, hav- 16, forming the support, is provided with l
